Diversity of human lip prints: a collaborative study of ethnically distinct world populations.

Background: Cheiloscopy is a comparatively recent counterpart to the long established dactyloscopic studies. Ethnic variability of these lip groove patterns has not yet been explored.

Aim: This study was a collaborative effort aimed at establishing cheiloscopic variations amongst modern human populations from four geographically and culturally far removed nations: India, Saudi Arabia, Spain and Nigeria.

Morphological patterns of lip prints in Saudi Arabia at Almadinah Almonawarah province.

In the past decades, lip-print studies (cheiloscopy) attracted the attention of many scientists as a new tool for human identification in both civil and criminal issues. The present work aimed to study in depth the lip prints of Saudi individuals (males and females) in Almadinah Almonawarah province. It is the first chieloscopic study done on Saudi individuals.
